The difference between air conditioning refrigeration and dehumidification

There is a big difference between the cooling of air conditioners and supermarkets. Because the long-term cooling of air conditioners will cause some condensation to form inside. If it cannot be removed in time in the pipes, it will lead to excessive moisture in the local area, and the air blown out by the air conditioner will be very unhealthy, so dehumidification and oxygenation are required regularly.

The vaporized refrigerant is compressed and liquefied by the compressor outdoors to release heat, and the heat is transferred to the outdoor air through the heat sink.

This continuous cycle achieves the effect of cooling the indoor air.

The air conditioner's control circuit has air temperature detection. When it detects that the indoor temperature is below the set temperature, the compressor stops working and enters the constant temperature control state.

Dehumidification is a side effect of air conditioning.

The principle is that when high-temperature air containing water vapor flows through the low-temperature evaporator fins, water is condensed. Of course, this process also occurs during the refrigeration process, and the water is condensed and discharged to the outside through the drain pipe.

The main difference is the program control.

The control basis of cooling is whether the indoor air temperature reaches the set temperature. As long as the temperature has not been reached, it will keep working until it is reached. At most, the air flow speed will be reduced when the indoor temperature is not much different from the set temperature.

There is no basis for the dehumidification work of air conditioners, only a process. In other words, when the air conditioner is dehumidifying, it only dehumidifies, regardless of how high the humidity is. Of course, the dehumidification working procedure control should achieve the most energy-saving and maximum dehumidification effect.

Since dehumidification also lowers the air temperature, it will also cause the indoor temperature to drop. In the dehumidification state, the compressor responsible for refrigeration does not work continuously, but dehumidifies intermittently, which makes the indoor temperature drop less than direct cooling.
